That Lunati "CJ" copy cam is pretty mild, I have one and it idles "smooth" at about 700 rpm, with a 750 holley.
The "Cheater cam" note rang a bell from the past so I poked around a bit...
Maybe it is this one? I don't think it will idle "smooth"!

"I've got an old Lunati 'Cheater' that goes about 248°Int/263°Exh @ .050", and a Cam Dynamics '-2' (stickshift)grind that's 252°Int/268°Exh. Lift on both runs about .003" to .009" below the .481"/.490" maximum."
"Since these also had to check legal at the 'gross' duration figures (304°/324° @ .002", you know that they were pretty radical looking lobes, leaving nothing to today's hydraulic roller designs. It's almost amazing they could work the way they did, turning 6,300-6,500 RPM with a whopping 296 lbs of spring pressure!"
